Preheat oven to 350.
Line a baking sheet with a silpat.
Place peanuts in a medium bowl (large enough to stir the peanuts).
Microwave honey and crushed red pepper in a bowl for 30 seconds and pour over the peanuts.
Add half of the sugar and the salt, stirring well.
Spread onto the baking sheet in a single layer and bake for 20 minutes, stirring every 5 minutes, making sure to stir the peanuts on the edges in to prevent burning.
Let cool for 2-3 minutes and then stir the peanuts, scraping the honey from the silpat to coat the peanuts.
Sprinkle with 2 Tbsp sugar and stir again.
Sprinkle with remaining sugar and let cool completely.
Break up the peanuts into single/smaller pieces and store in an airtight container.
